Percutaneous pulmonary valve replacement: autologous tissue-engineered valved stents.
AIMS Percutaneous implantation has already been used clinically and is a great option for treating young patients. The use of autologous tissue-engineered valved stents might solve the problem of degeneration and limited durability of biological heart valves. METHODS AND RESULTS Porcine pulmonary heart valves and small intestinal submucosa were obtained from a slaughterhouse. The intestinal s...
متن کاملPercutaneous valve replacement: a novel low-profile polyurethane valved stent.
Fig. 1. (a) Oblique view from top of a self-expanding nitinol stent (length 28 mm, diameter 24 mm, Nitinol Devices & Components Inc., Fremont, CA, USA) containing a three leaflet polyurethane valve. Leaflets have a thickness of approximately 100—150 mm. The stent valves are produced in a dip coating technique (by Mecora GmbH, Aachen, Germany). (b) Low-profile polyurethane valved stent was folde...
متن کاملPercutaneous aortic valve replacement: computed tomography scan after valved stent implantation in human cadaver hearts.
Computed tomography scans were performed before and after aortic valve resection with consecutive implantation of a valved stent in human hearts with highly calcified aortic valves in situ (n=2). This demonstrates that the valved stent shows better fitting in the annulus after removal of the native valve.

INTRODUCTION Percutaneous pulmonary valve implantation (PPVI) is one of the most exciting recent developments in the treatment of structural heart disease and has evolved as an attractive alternative to surgery in patients with dysfunctional right ventricle-pulmonary artery conduits. Although surgical pulmonary valve replacement is associated with low morbidity and mortality rates, there are ma...
متن کاملPercutaneous Pulmonary Valve Implantation
Pulmonary regurgitation (PR) is a frequent sequelae after repair of tetralogy of Fallot, pulmonary atresia, truncus arteriosus, Rastelli and Ross operation. Due to patient growth and conduit degeneration, these conduits have to be changed frequently due to regurgitation or stenosis. However, morbidity is significant in these repeated operations. To prolong conduit longevity, bare-metal stenting...
